Rubus recurvans is an uncommon North American species of brambles in the rose family. It is found in eastern and central Canada (Québec, Ontario, Nova Scotia) and in the eastern and north-central United States (from Maine west to Minnesota, south as far as Missouri, the Ohio River, and Virginia).
Rubus recurvans has perennial roots and biennial stalks. Stems and the undersides of the leaves are covered with a thick layer of yellow-green hairs. Leaves are compound with 3 or 5 leaflets. Flowers are white. Fruits are black and cylindrical.
The genetics of Rubus is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy.
